Re: Frequency in SDRUno and hardware drift apart

I assumed it was operator error, or that I had changed a setting somewhere. If I can find a simple sequence of actions to create the discrepancy, I'll give support a try.

As it is, I'm really enjoying the RSP2, my first foray into SDR.

Re: Frequency in SDRUno and hardware drift apart

Just to update my first post, Yesterday I came across a faint English language station, but the frequency was clearly wrong in an area of the bands where broadcast stations simply don't operate. Usually it happens after an explore of various frequencies where I'm typing in a frequency directly, spot...

Re: Poor RX Signals on the RSP2

I've been happy so far with HF reception on my RSP2 Pro, especially having to tackle QRM in the area.

I've used a Wellbrook loop through the Hi-Z port and A terminal, the Hi-Z working best, and making sure the RF Gain reduction is at an appropriate level.

Re: How to Decode Digital Modes Reliably

Some additional information. I set up my own short range experiment using a dummy load, and tried different different decimation values. Images were largely upright except decimation 1 which had some very odd distortions. 2 looked pretty close, but 4 and 8 had some odd slants. Of course there was no...

How to Decode Digital Modes Reliably

I used my RSP2 Pro in anger for the first time yesterday to receive and record a digital modes broadcast consisting of MFSK32 text, images and Olivia modes. The result from the human ear perspective was good although with periodic audio stutters. For computer decoding however, the recording was almo...

Frequency in SDRUno and hardware drift apart

Bought my RSP2 Pro from MLS yesterday, spending today getting into it. A couple of niggles so far, the most important being that the frequency displayed in SDRUno seems to get out of step with the hardware. At startup, all is fine, but during the process of changing frequency through a combination o...
